Thecasing is provided with a flange 26 for engagement with the guide. rollers which hold the casing in position and cause it to run true, and a tubular bearing'member 27 which is mounted on a which the end of the film is inserted, and is also provided with a spring clip 30 beneath which the end of the film is secured to firmly. .fasten the film to the casing or reelr The stud or shaft 28 secured to. the bracket 10 film feeding'mechanism' 12 comprises two 1 sets ofspur feed whee1's'31and 32 between which the 'film extends in the form of a loop as shown in Fig. 1, whereby the film is caused to enter the casing 11 without undue bending or distortion.

The film guide mechanism l4 comprises a guide'member 33 which is" pivotally mounted as shown at 34 on a support or bracket'35 which is mounted ontheslide which carries the mechanism 15; The mechanism 15, for causing the film to be :reeledup inside of the casing 11, comprises a friction roller 36 (the suiffacefof which may be formed of any suitable material such as a soft rubber composition which will not injure orblujr the film) rotatably mounted on a shaft or, stud 37 which is secured on a support 38 slidably mounted on the arm 18 of the bracket 10. The support 38 is provided with wing portions 39 which extend around and embrace the arm 18; lugs 40 extend from these Wings 39 and to these lugs are secured rods 41 which extend through guide openings in a web 42 formed mechanism 15 comprises a belt 47 which is driven from the cameragraph, a pulley 48 driven by this belt, a shaft 49 on which the polls 48 is secured, a spur gear 50 also secure on the shaft 49, a wide faced spur gear 51 meshing with the gear 49, a shaft or stud 52 on which the gear 51 is mounted, a gear 53 meshing with the gear 52, a shaft 54 on which the gear 53 and spur feed wheels 31 are secured, a gear 55, a shaft 56 mounted in suitable hearings in the bracket 10 and on which the gear is secured, a sprocket or pulley 57 secured on the shaft 56, a flexible driving member 58 which may be formed from a continu'rius coiled spring, the coils of which engage recesses in the periphery of the sprocket or pulley 57, and a sprocket or pulley 59 similar to the sprocket 57 which is driven by the flexible member 58 and secured so as to cause the roller 36 to rotate with it. A pair of guide rollers 60 are provided for holding the reel against the teeth of the spur feed wheels 31 and 32. These rollers are mounted on studs 61 secured to supports 62 which are slidably mounted on the arm 22, by means of wing portions (53 extending around the arm. One of these wing portions is provided with a lug (54 to which is secured a rod 65 which extends through an opening in a web (56 on the arm 22. A spring 67 surrounds the rod (35 and bears against the lug (34 to hold the roller 60 against its spur wheel. Two pressure rollers (58 are provided for holding the film within the casing 11 and for engaging the llangc 26 of the casing to cause the latter to run true. These rollers (38 are rotatably mounted in bearings (59 which are secured to the rods slidably mounted inopenings in the bracket 10 and bracket 70 which is secured to the bracket 10. Springs 71 are provided for holding the rollers 68 -against the flange 26, these springs engaging the bracket 70 and bearing against pins 71 in. l

the rods 70. The guide member 33 comprises two Jarallel leaf portions 73 between which the lm extends, and a wing portion 74 which extends upwardly to engage the edges of the film which are within the casing 11 to prevent them from slipping out of the casing.

The film valve 17 comprises a pair of rollers 75 one of which is pressed against the other by means of a spring 76 and between which rollers the film is led into the casing 16. The supply reel 77 (Figs. 5 and 6) from which the film is fed to the cameragraph is so constructed that the film, after it has been reeled up inside of the casing 11, may he slipped from the casin 11 onto the reel 77 without any necessity for rewinding the film. To accomplish this result the reel is made of two separable portions which have a telescopic connection with each other. The reel comprises two flanges 78 and 79 between which the film is received, a tubular bearing member 80 secured to the flange 78 and two telescoping cup shaped members81 and 82 secured to the flanges 78 and 79 respectively. The casing 11 may be held on the stud 28 in any suitable manner as by means of a pin 83 (Fig. 2).

The use and operation of my improved apparatus is as follows: The end of the film from the supply reel is threaded between the rollers 75 of the film v'alve into the casing 16 and the film is then placed in position between the spur feed wheels 31 and 32 and their corresponding pressure rollers 60 as shown in Fig? l, the film being slack between the two rollers to give it the right direction to enter the casing 11 without unduly bending or (llS-)I'tlI1g the film. The end of the film is then inserted through the opening 25) in the casing 11 and secured beneath the spring clip 30 to hold it securely The casing 11 is then on the casing 11. slipped in place on the shaft 28, the film 13 being placed between the cylindrical portion 24 of the casing ll and the friction roller 36, the film at the same time being placed between the leaf portions 73 of the guide 33. The casing 11 is then secured in place on the stud 28 in any suitable manner as by inserting the pin 83 through the end of the stud 28. The machine is then put in operation to feed the film through the cameragraph. This operation of the machine drives the bolt 47 which in turn causes the feed wheels 31 and 32 to be operated through the inter 50 reel as soon as it has been run through the inseam" wheels- 31 and 32 is taken up and reeledup insideoi the casing 11 by means of the fricvtion roller 36 which is also driven'from the vbelt 47 throughintermediate driving mechanisms including the pulley 48, shaft 49,

itself to the position assumed by the film.

. After the film has been run through the cameragraph and wound up within the casin 11 the casing containing the film is slipped off of the stud 28, the end of the film is freed from the clip 30 and the entire film the'casing'll onto the special supply'reel 7 I as shown in Fig. 6. The

- It willbejnoted that with my improved take-up mechanism it is not necessary to re slipped from the take-up wind the film from the take-up reel onto a supply reel, but that the film can simplybe reel onto the supply -reel. This makes the. films last much longer as the rewinding is hard on the films. It also saves .the laborand time of rewinding,

and enables oneman to operate the machine,

as the film is reeled up in such a mannerthat it is ready to be again placed in a supply.
